A pub which was all set to open with a licence it had secured from a Suffolk district council, was forced to abandon its opening when officials pointed out the pub was actually in Essex.
The Mitchells & Butlers pub, the Haver Arms, received a licence from St Edmundsbury Borough Council and had planned a grand re-opening.
However, at the last minute it was pointed out that the licence was invalid because the pub was over the border and into Essex.
Licensee Dee Morris told the Cambridge Evening News: "It has been a nightmare."
The pub's staff are being paid until it can re-open with a new licence from Braintree District Council, which is expected on February 23.
A spokesman for Mitchells and Butlers told the paper: "We have been unlucky.
"It is unusual, but we applied to the council we thought was the right one."
A spokesman for St Edmundsbury Borough Council said: "We received an application for the Haver Arms. A license was issued in error when we believed the premises to be in the borough."
